Problems solved by technology

[0003] However, there is no suitable method in the prior art for the inspection of a huge structure like an airplane, and the method mainly uses manual ultrasonic inspection equipment such as visual inspection and palpation, or liquid immersion inspection and manual scanning.
Any of these methods is inefficient and relies on the feeling of skilled workers in many cases, resulting in problems of low work efficiency and low inspection accuracy.
With these conventional inspection methods, it is difficult to obtain objective data that can analyze and evaluate the history after participating in the voyage, and there is also a problem of quality assurance
[0004] In addition, a part of the prior art implements X-ray body non-destructive inspection, and the X-ray method requires a shielding structure that is not irradiated with radiation, so there is a small body that is limited to jet aircraft and the like, and can only be Issues with conducting inspections at restricted locations

no. 1 Embodiment approach

[0021] The aircraft body inspection apparatus of this embodiment has an inspection vehicle equipped with a laser system, a 6-axis manipulator robot that holds an ultrasonic probe, a lifting mechanism that moves the robot in the vertical direction, and the robot in a horizontal position. A horizontal movement mechanism that moves in a direction, the inspection vehicle can move in the front, back, left, and right directions and can freely access the aircraft body. The inspection vehicle is positioned relative to the aircraft body through the laser system. The actions of the robot, the lifting mechanism, and the horizontal movement mechanism are controlled by a control device through a wireless remote transmission system. The ultrasonic waveform data obtained from the ultrasonic probe is transmitted to the control device through the wireless remote transmission system, and the calculation is performed according to the flaw detection conditions preset in the control device and the res...

no. 2 Embodiment approach

[0037] use Figure 7 ~ Figure 9 The second embodiment will be described. Figure 7 (a) is a plan view of an embodiment in which two trolleys 11 are arranged side by side and a laser system and an ultrasonic probe are mounted on a horizontally movable horizontal movement mechanism 40, Figure 7 (b) Yes Figure 7 (a) side view.

[0038] In addition, since the ultrasonic non-destructive inspection device for an aircraft body according to claim 2 can connect multiple vehicles through a horizontal movement mechanism corresponding to the inspection area of ​​the aircraft body, it has the ability to efficiently obtain more information through a single setting. The advantages of a wide range of inspection data can greatly improve the efficiency of inspection operations.

[0039] Figure 8 with Picture 9 Is to use 2 or 4 Figure 7 According to the configuration of the inspection vehicle 10 shown, the inspection can be performed at multiple locations while improving the inspection efficien...

Abstract

The object of the present invention is to provide an aircraft body inspection method and device that can accurately conduct efficient and non-destructive inspection of the aircraft body without relying on visual inspection and palpation. It is composed of: an inspection vehicle (10), which can move forward, backward, left and right in the horizontal plane; a laser emitter (32), which is loaded on the inspection vehicle (10), irradiates the aircraft body (1) to be inspected with laser light and receives reflections Light; an ultrasonic detector (13), mounted on the inspection vehicle (10), emits ultrasonic waves to the aircraft body (1) and receives reflected waves; and a control device (35), which controls the inspection vehicle by signals from the laser emitter (32) (10) moves and displays ultrasonic inspection data of the aircraft body (1) by signals from the ultrasonic detector (13).

Description

Technical field [0001] The invention relates to an inspection method and device for an aircraft body, which not only performs non-destructive inspection on the surface of the aircraft body during the manufacturing stage of the aircraft and after entering the operational flight operation. Background technique [0002] Conventional aircraft bodies were mainly composed of metal materials mainly composed of duralumin and aluminum alloys or their composite materials. However, recently, from the viewpoint of flight economy and environmental pollution countermeasures, CFRP (Carbon Fiber Reinforced Plastics) has been adopted to further reduce the weight of the aircraft body. Reinforced plastic) materials. Generally, the strength characteristics of the CFRP material itself are sufficient as flight performance. However, it is often preliminarily checked whether there is any abnormality in the adhesion between the CFRP layers caused by the aging degradation after participating in the sailin...
